The tagged message API uses a tag and a mask to identify messages. However, applications are really using the tag space as a collection of independent fields. For example, 32-bits may represent the message, 16-bits the source address, and 16-bits as a group address. By exposing the use of the fields to a provider, it enables additional optimizations within the provider. For example, a provider could maintain separate queues, to greatly improve search times. Define a mechanism by which the app and provider can communicate the number of fields and their size.
